chisel 編譯錯誤：對象插件不是 chisel3.internal 包的成員

Question

我正在通過一個小型試驗項目學習 chisel3。

我寫完代碼，在編譯中修復了幾個語法問題，然后報錯，沒有指明錯誤文件和行號。

$ sbt test

這是什么意思？ 請幫忙。

Answer 1

我剛剛發現，在build.sbt中更改chisel3版本后錯誤消失了。

    libraryDependencies ++= Seq(
      "edu.berkeley.cs" %% "chisel3" % "3.4.3",
//      "edu.berkeley.cs" %% "chisel3" % "3.2.6", // this one generate plugin error above
      "edu.berkeley.cs" %% "chiseltest" % "0.3.3" % "test",
      "edu.berkeley.cs" %% "rocketchip" % "1.2.6"

以前我從 3.4.3 更改為 3.2.6 因為 sbt 警告

[warn] There may be incompatibilities among your library dependencies; run 'evicted' to see detailed eviction warnings.

我跑了 sbt evicted，它說 Rocketchip 1.2.6 應該使用 chisel3 3.2.6。

也許有人可以澄清。
